Set user lockout
attributes

If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).

In the left
pane select Security Realms.

On the
Summary of Security Realms page select the name of the realm (for
example, myrealm).

On the Settings for Realm Name page select
Configuration > User Lockout.

Modify
default values on this page.

If the number of invalid login attempts for a user account
exceeds the value set for the Lockout Threshold attribute on this
page, the user account becomes locked. Specify other attributes on
this page to modify how the number of invalid login attempts is
calculated. For information about unlocking the account, see Unlock user
accounts.

Click Save.

To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
